T0 ttl/ wiz/0m it may concern:

A Be it k nown'that l, VALENTIN LAPP,brewer, a subject of the King ofSaxony, residing at Lindenau, near Leipsic, in the Kingdom of Saxony, inthe German Empire,have invented a new and useful Process ofltlanufacturing Non-Alcoholic Beer, ot' which the following is aspecification.

This invention relates to a process of man ufacturing non-alcoholicbeer, and in turning this invention into practice l make use of theapparatus shown in the accompanying drawing, the parts of which will bementioned in the detailed description following.

Vort produced according to any known method is led into the pan a andtherein boiled, as usual, whereafter it is pumped to and into a vessel cby means of a pump b, the wort being mixed under the way with a rathergreat quantity of air, preferably two cubic meters per minute, forceddirectly into the connecting-pipe n. The rate at which the wort is beingpassed through this pipe amounts to one meter per second, itbeingassinned that the width in the clear of the pipe n amounts toforty-six millimeters. The vessel c is provided with an exhauster cl forleading away the liberated vapors and Ihe steam. r indicates the pulleyby which the exhauster is actuated. The wort, which has thus beenthoroughly aerated by the air, isled from the Vessel c into acentrifugal machine c and is therein saturated with ozone generated inan ozonizing apparatusf. From the centrifugal machine e the hot wort ispassed through a conduit g to a closed coolingr vessel 7L. The ozonizeror ozone-generating apparatus f may be ot any desired kind andconstruction; but it is necessary that of the diluted ozone which suchan apparatus merely can produce, or, more precisely, of the quantity otdiluted ozone which the apparatus can produce in an hour, fifty grams beactual ozone. 'lhe percentage of actual ozone in the diluted ozone mayhe ascertained by any desired of the known methods, and thereafter somuch air should be conducted to and into the diluted ozone as originallyproduced in and by the ozone-generating apparatus that titty grams ofactual ozone are contained in twenty cubic meters of air. This air mayat the same time be used for introducing the ozone into and mixing itwith the hot wort. For this purpose use may be made ot' an ordinary jetapparatus, such as indicated at 0, which is insei-ted into the pipe s,connecting the ozonizer f and the centrifugal machine e. The air isforced in through the lateral pipe p, and in passing over into the lowerpart of the pipe s it draws with it the ozone from the upper part ofsaid pipe, all proportions being so determined that the pipe p receivestwenty cubic meters of air in one hour, and this air draws with it fiftygrams of ozone in the same time. The jet apparatus 0 maybe located, ifdesired, at the upper or at the lower end of the pipe s, either above orwithin the centrifugal apparatus, and it may be replaced by any otherdesired cont-rivance adapted to finely distribute the ozone in the wort.During its way through the conduit g the hot wortI is impregnated withCO2, contained in a steel flask t. The latter is connected with theconduit g by a pipe tu, and near to the head of said flaskareduction-valve c is inserted in said pipe. The valve 0J is so adjustedthat the carbonic acid escapes with a pressure of ten atmospheres, andthe wort liowing into and contained within the cooler h is thussubjected to that pressure. The wort when entering the vessel or coolerh is cooled at once to below zero,(centigrade scale.) The purpose ofthis treatment is the following: By quickly and intensely cooling theliquor produced in the aforedescribed manner the disadvantageousalbumiuous bodies and the like dissolved in the liquor are precipitated,and this precipitation is promoted and accelerated by the high pressureemployed. Owing to this process, the beer becomes clearer, keeps good alonger time, and attains a higher quality. After the liquor has beencooled it is made to pass through a iltering apparatust' and then ledinto a saturating apparatus 7c, in which it is saturated with carbonioacid. Thereafter it is made to pass through another filtering apparatusZ. The beer, still saturated with carbonic acid, is then led into avessel m and therein subjected to a pressure of about ten atmospheresand finally it is bottled or racked off, the air contained in the caskshaving prior thereto been removed. Owing to this means, the bottling orracking-oft of the beer proceeds easily and without any excessivegeneration of froth. The effectof the second pressure of about tenatmospheres consists in a remarkable improvement of the appearance andtaste of the beer. p

From the commencement of the introduction of the product into the vesselc the product is kept ont of contact with the outer air through allsubsequent phases of the process and in all other parts of the apparatusand is finally led in a perfectly sterile state into containers that arecompletely avoid of air.

Having now described my invention, what I desire to secure by a patentof the United States is- The method of manufacturing non-alcoholic beer,consisting in heating Wort, veny 4 VALENTIN LAPP. Witnesses:
